Ice can



B. PHILLIPS ICE CAN Filed Mar. 2B, 1921 Cri l to require a minimum ot solder, vthus mali 10E CAN.

To all eli/10m 'may concern:

Be it known that l, Bietigheim l'liiinmrs, a citizen or" the Unite'l dtates, residingj- Cincinnati, in the county oi? Hamilton and the State of Uhio, have invented certain new and nsetul improvements inl loe Cans; oi which the tollowing is a speciiication.

t'iy invention relates to ice cans 'ik 1 'treecing ot ice in relirigeratingg sy where the can is filled with water placed in a :freezing brine solution. llhe brine moreoverexerts a powerful corrosive action on ferrous metals.

l-leretotore, it has been the practice to employ ice cans made of sheet metal coated with a non-corrosive metal, such as Zinc, in the Yform ot galvanizing,v known as galvanized iron. Also, they have not been so constructed as to avoid leakage through the seams due to corrosion after a period ot aise, which permits the brine to enter the interior oil the ice can and destroy the purity ot the water, delaying;` the ltreeaaing thereot. The cans heretotore made have had their joints held together by rivets. The brine rapidly corrodes the rivets causing the joints to open7 shorteningvthe lite of the can. Another method that has been employed, isto secure the oints by welding'. This has not been tonnd tombe satisfactory, in that the structure ot the metal itselt is changed at the weld.` The difference in expansion and contraction between the metal at the welds, and the surrounding metal causes opening ot the joints, thus permittingI the brineto enter.

Une ot the objects ott my invention is to provide an ice can so constructed as to be ot `great durability and have no obstructions on the outside thereof. so as to avoid interference with other cans placed adjacent thereto,

Another object oit vmy invention is to pro vide a can constructed with interlocking seams yat the joints, so as to be absolutely water-tight, and yet readily assembled and soldered. j

lt is another object ot my invention to so construct the seams as to lend additional strength to the can, and also to term these seams in their` relation to one another5 as inp; a very economically constructed can. I

rroter incre particularly to the verticalv seams i Y A l s n l tty :3x-wen non consists in constructing j an ice can, having one or more vertical seams held together by a specially formed Closure vand combination and arrangement thereof,

as herein'described and claimed.

Fig. T is a plan view ot the bottom ol one corner oit'` my improved ice can laid out in plane to show the contour ot the edges.

Fig. 8 is a perspective view of one oi the lower inside corners ot the ice can, with the bottom removedc showing the `n'ianiier in which the lower edges Vare termed.

Fie. Q is a perspective view oit one ot the corners ot the bottoni ot the ice can,V showing the manner in wl'iich the edges thereof are toi-ined preparatory rto assembling.

Fig, l() is a perspective view oit the lower `inside corner ott acompleted ice can, shown 'il My improved ice can comprises a casing l5, eonsistin@ of vsides 16 and ends l?. T he sides and en s may be formed ot one or more sheets joined by vertical seams lS. l have illustrated my improved ice can having' one vertical seain, but it is obvious that a seam can be made at all oil the corners.` rlhe seam 18 is made Vas by having the edges ot the Sheet -formed into flanges i9 parallel therewith. The iianges and the portions ot the sheet adjacent thereto 'form channels 20. The bottoms oif the channels are 'formed bv bends 2l which join the iianges tothe sheet.

Depressione 22 torni the inner walls ot the channels, and are connected to the main body ot the sheet by double bends 23, which greatly add to the strength and rigidity ot sides. The depressions also torni a means whereby the closnre'strip, lnreafier described, is held more iirin'ly in place.

For closingthe seam. a closure strip 25 comprises side walls 26 connected by an angular corner wall 2T. Flanges 28 parallel to theside walls 2G are connected by bends 29 to iorm channels Sd The closure strip is adapted to be forced over thenanges onk the casing of the ice can. lThe flanges 18 on the easing4 enter the channels 30 on the Closure strip, and the flanges 28 on the closure strip enter the channels 2O on thevcasing, thus securely joining'the edges oit the casingto forni an interlocking seam.

' The side walls 26 have extensions 8l on their lower end for purposes hereafter described.

4 After the seam has been formed, a body ot solder is run into the inside corner, iilling np the space 34 formed between the angular corner wall 27 on the closure strip and the bends on the casing. A fillet 35 is formed in the corner ot the can by the solder, lendingadditional strength to the sea-rn. The Hat corner wallcloselyv follows the contours ot the bends 2l and a line tangent thereto, pro- 'looking the bottom in place.

viding a stronger connection than if the side walls oi: the closnre strip were continued to meet at a sharp corner. The space occupied by the solder' is therefore greatly reduced forming a very econor'nioalv method of inaking a water-tight seam.

The bottom wall 3G ot the eanconiprises a main portion 37 having extensions 38 on the four edges thereof.` Each oi the extensions `consists of down turned portion 39, np-

tiirned portion 40, horizontally turned portions 41 and a closure flange 42. The horizontally turned portions have niiters 45 on each ot their respective ends. The closure flanges have miters 46 on their ends. In forming the edges of the bottoni, the closure flanges 42 are bent downward on the dotted line indicated at a (see Fig. 7). The horizontal portions 4l are then bent on the dotted line o. The upturned portions 4G are. next bent back onthe downturned portion on the dotted line 'lhe downtni'ned portion is then bent at right angles to the main portion 3T on the dotted line 05, the horizontal portions 4i contacting the bottom of the main portion. The dov itnrned potions and the ngtnrneei portions together form downwardly 'projecting flanges 4T on the ex' renie edges oi the main portion. XM1he flanges 4T together with the horizontal portions and the closure flanges 42 it rm channels The ruiters 45 and i6-on the horizontal portions and clos e ilanges spectively, permit them to lie .n eoineident planes.

Y.tach of the sides oit the are provided with extensions 50. lilach oit the extensions coniprses a horizontal portion nptnrned portion 52, and horizontally 'turned iianges 53. The extensions are bent at right angles on the dotted line indicated at e (see Fig. 6), to form horizontally turned flanges 53. The npturned portion 52 is bent at right angles to the iianges 53 on the dotted line f The horizontally turned portions 5l are bent yon the ydotted line g vand `torni a connection between the uptnrned por tions and the sides oit thecasing. The'portions 53 have niiters 54 on their respective ends and the horizontallyturned portions 5l have miters 55 on their ends permitting them to lie in coincident planes. The horizontally turned Vportions 51 and vertically turned portions 52 form channels 56 along the lower edges of the casing and parallel thereto. v

The bottom, formed as described, is placed within the casing and forced downward until the flanges 4T enter the channels 56. The uptnrned lportions 52, and the horizontal iianges on the bottom, enter the channels 48 on the bottom wall. The downwardly depending closure flangesy 42 are then turned over the horizontal. flanges 53 on the easing and lie flat thereon, effectively The coacting channels and iianges ,form interlocking seams, providing an extremely rigid reinforcement for the bottom ofthe ice can.

iter the bottom hasbeen locked in place, solder is run into the rcorners so as to Jform fillets 58. After the bottoni seams are closed, the extensions 31 on the closurestrip are bent over the edges on the seaniand soldered inplac'e forming an additional means for securing the closure strip andl providino against` its dislodginent. The solder and the interlocking flanges and channels, form extremely light weight and durable waterf tight seams in the bottom of the ice can.

,The upper edges of the tank are rein forced by a heavy metal band 60 held in place by rivet 6l. The heads of the rivet are `preferably countersnnk as shown at 68 on the voutside of the band, and the heads of the rivets on the inside of the tank are prefeiehly oountersnnk lowei` than the Surface iis shown zit 62. L body oi soldei is inn into the cavity thus foi-ined to p-iesei've 'them against corrosion. This part of the tank,`

ho'wevel, does not entei into the brine, theieloi-e the corrosive action is ieduoed to :i inininiuin. Holes 63 in the bend coinciding with holes G- in the sides oi'i the casing, provide :i ready means ii'oi' giesping 'the iee een with suitable hooks and tackles, is the practice to employ in ieliigei'ating plante.
